Stems can get you high, its just that not as much THC is in the stems as is the regular buds. The only problem I've found with getting high off stems is that I get a light headache afterwards, and it tastes like I'm smoking a campfire. So, thats why I don't do it. One time I had about an ounce of stems, grinded ALLLLL of them up in a coffee grinder and then packed that into a bowl, it got me pretty buzzed, but the taste was such a turn off that I just threw the rest of the stems away..................and got out my tools to start gettin resin from my baby!

.............only to give up 10 minutes later and lay in my bed moderately high, HA! God, I'm such a lazy fuck. lol
